A GoPro weighs only ounces. the camera making the Howard Hall video probably weighed 30-60 lbs. Inertia is his friend.
I teach and have played my videos on my projection board. As an approximately 4' x 8' image the camera shake was a lot worse than it was looking at it on my laptop.
what I would like to find is a software package that I could take the video from camera to finished video with de-shaking included. I played around with V-dub, which is supposed to work well on gopro files, but you need to file convert in the gopro editor, then send it through v-dub and then edit it in a software other than the gopro editor. After spending several hours making the stabilized files, I ended up chucking it when I was unable to get the files into a format I could use with the editor I was already familiar with.
I would consider buying something(~$50-60) if I could just do the entire thing in a single software package from camera to up upload ready. Anyone know of a package like that?
